1. A nurse is assessing a patient with suspected heart failure. Which early
clinical manifestation is most indicative of left-sided heart failure?
A. Jugular venous distention
B. Peripheral edema
C. Crackles in the lung bases
D. Paroxysmal nocturnal dyspnea
Rationale: PND is an early sign of left-sided heart failure due to pulmonary
congestion. JVD and peripheral edema are signs of right-sided failure. Crackles
occur later as fluid accumulates.
2. Which diagnostic test is the gold standard for confirming a diagnosis of heart
failure?
A. Chest X-ray
B. BNP level
C. Echocardiogram
D. Cardiac catheterization
Rationale: While BNP and echocardiograms are useful, cardiac catheterization
remains the gold standard for hemodynamic assessment and diagnosis of heart
failure.
3. A patient with chronic stable angina is prescribed sublingual nitroglycerin.
What is the most important instruction the nurse should provide?
A. "Chew the tablet for faster absorption."
B. "Swallow the tablet with a full glass of water."
C. "Take up to three tablets 5 minutes apart; call 911 if pain persists."
*D. "Place the tablet under the tongue and allow it to dissolve; repeat every 5
minutes up to 3 doses." *
Rationale: Sublingual nitroglycerin is absorbed through the oral mucosa. The
standard protocol is one tablet every 5 minutes for up to 3 doses, then seek
emergency care if pain continues.
4. Which medication class is considered first-line therapy for managing chronic
stable angina?
A. Calcium channel blockers
B. ACE inhibitors
C. Diuretics
D. Beta-blockers
Rationale: Beta-blockers reduce myocardial oxygen demand by decreasing
heart rate and contractility, making them the first-line agents for chronic stable
angina.
5. A patient with acute coronary syndrome (ACS) is started on aspirin and
clopidogrel. Which adverse effect should the nurse monitor for closely?
A. Hypotension
,3|Page
B. Hyperglycemia
C. Tachycardia
D. Bleeding
Rationale: Dual antiplatelet therapy significantly increases the risk of bleeding.
The nurse should monitor for gastrointestinal bleeding, bruising, and
intracranial hemorrhage.
6. In the management of ST-elevation myocardial infarction (STEMI), what is
the goal for door-to-balloon time?
A. 30 minutes
B. 60 minutes
C. 90 minutes
D. 120 minutes
Rationale: The American College of Cardiology recommends a door-to-balloon
time of ≤90 minutes for primary PCI in STEMI to minimize myocardial damage.
7. A patient presents with "crushing" chest pain radiating to the jaw,
diaphoresis, and nausea. What is the priority nursing action?
A. Administer morphine IV
B. Obtain a 12-lead ECG
C. Draw cardiac enzymes
D. Administer aspirin 324 mg chewed
Rationale: Aspirin reduces mortality in ACS and should be given immediately
upon suspicion of MI. ECG and enzymes are important but secondary to
antiplatelet therapy.
8. Which finding on an ECG is most characteristic of a STEMI?
A. Peaked T waves
B. Widened QRS complex
C. ST-segment elevation
D. Prolonged PR interval
Rationale: ST-segment elevation in two contiguous leads indicates transmural
myocardial infarction (STEMI).
9. A patient with heart failure is prescribed furosemide. Which laboratory value
requires immediate intervention?
A. Sodium 136 mEq/L
B. BUN 18 mg/dL
C. Potassium 2.9 mEq/L
D. Creatinine 1.0 mg/dL
Rationale: Furosemide is a loop diuretic that can cause hypokalemia. A
potassium of 2.9 is critically low and increases the risk of arrhythmias.

10. Which dietary restriction is most important for a patient with heart failure?
A. Fluid restriction to 1 L/day
B. Low-fat diet
C. Sodium restriction to <2 g/day
D. High-fiber diet
Rationale: Sodium restriction reduces fluid retention and decreases the
workload on the heart. While fluid restriction may be used, sodium restriction is
universally recommended.
11. A patient is diagnosed with unstable angina. Which intervention is most
appropriate initially?
A. Administer thrombolytics
B. Initiate heparin and antiplatelet therapy
C. Prepare for CABG
D. Insert a temporary pacemaker
Rationale: Unstable angina is managed with anticoagulation (heparin) and
antiplatelet therapy to prevent progression to MI.
12. A nurse is caring for a patient with an acute MI who develops hypotension
and muffled heart sounds. What should the nurse suspect?
A. Papillary muscle rupture
B. Ventricular septal defect
C. Cardiac tamponade
D. Acute pericarditis
Rationale: Muffled heart sounds with hypotension suggest cardiac tamponade,
which can occur post-MI due to pericardial effusion.
13. A patient with chronic heart failure is on digoxin. What is a sign of digoxin
toxicity?
A. Tachycardia
B. Hypertension
C. Hyperkalemia
D. Visual disturbances (yellow halos)
Rationale: Digoxin toxicity presents with GI symptoms, bradycardia, and visual
disturbances such as yellow-green halos.
14. A patient with unstable angina is prescribed ticagrelor. Which adverse effect
is unique to this medication?
A. Thrombocytopenia
B. Neutropenia
C. Dyspnea
D. Hepatotoxicity
Rationale: Ticagrelor can cause dyspnea due to increased adenosine levels,
which is a unique side effect compared to other P2Y12 inhibitors.
